Nyssa and Doctor unlock antimatter gateway

Nyssa deciphers cryptic TARDIS data-bank entries revealing the Rondel region’s true nature as the Arc of Infinity, a rare collapsed Q star exhibiting quardal magnetism that can shield antimatter. The Doctor synthesizes the clue, deducing the creature’s dimensional entrance point and the instability of its force field. Their research exposes the Arc as both gateway and vulnerability—the creature’s existence tied to the Doctor’s biodata and Gallifrey’s manipulations. Realizing the threat’s cosmic scale, they grasp the impending fusion will erase his timeline unless the transdimensional bond is severed.

Key Dialogue

"NYSSA: Rondel, intergalactic region devoid of all stellar activity. In former times the location of collapsed Q star."
"DOCTOR: They're very rare. On burnout it creates quardal magnetism. That's what the sensors picked up. It's the only force known to shield anti-matter."
"DOCTOR: That's it, Nyssa. That's how it came through. What we saw was the gateway to the dimensions. The Arc of Infinity."
